On the dole and thinking of moving to a different county. Implications?

Hi i am on the dole recently and want to move up to Galway city from Tipperary to live with my girlfriend and start a course.

My problem is that i will be staying at her place and was wondering how do i change my address to her place if I am not on the lease agreement or have any bills in my name.

Is there any way around it?

Is there any implications for social welfare?

Benefit or Allowance?

jobseekers allowance

If it's allowance, you'll be means-tested on your girlfriend's income, so your payment may be reduced or stopped depending on what her income is.

thanks for d advise
